Sticking together

Spotted this collection of Canada Geese on the water of the Test river estuary today - do you call them a gaggle. They were in the distance and constantly swimming back and forth it was impossible to count their number.
But certainly more than I have seen in one place before.
The water meadows and marshlands of this part of the river are home to varied species of birds. Yet even in the distance it was quite a spectacle.
